mac80211: Only accept data frames in OCB mode
Currently OCB mode accepts frames with bssid==broadcast and type!=beacon. Some non-data frames are sent matching this, for example probe responses. This results in unnecessary creation of STA entries. Signed-off-by: Bertold Van den Bergh <bertold.vandenbergh@esat.kuleuven.be> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
